Method for processing automobile rear torsion beam on horizontal boring machine

Abstract

The invention discloses a method for processing an automobile rear torsion beam on a horizontal boring machine to solve the problem that the automobile rear torsion beam is required to be processed on special equipment or a five-axle processing center. The method is characterized in that: a boring cutter is changed into a disc milling cutter, and a space angle to be processed is synthesized by using a rotary table of the horizontal boring machine and a tool angle, so that the outer sides of hub supports on two sides of the automobile rear torsion beam are processed. By organically combining the ingenious design of a tool and the functions of a cutter and the rotary table of the boring machine, the space angle machining of the automobile rear torsion beam is finished on a common horizontalboring machine. By using the method, the investment pressure of early-stage sample piece processing can be reduced, the equipment purchasing cycle can be shortened, and the demand of the sample pieceprocessing can be met. The method is also suitable for the small scale production of the automobile rear torsion beam products.

Description

technical field [0001] The invention relates to a method for processing automobile parts, in particular to a method for processing rear torsion beams of automobiles on a horizontal boring machine. Background technique [0002] The function of the rear torsion beam of the car is to bear the rear load of the car, support and drive the rear wheels to rotate and turn the car. The rear wheel positioning of most cars is not adjustable, and its positioning is completely guaranteed by adjusting the toe angle and inclination angle of the rear torsion beam. At the same time, when the car is running, the rear torsion beam bears variable impact loads. Therefore, It is required to have high strength and is an important security part of the car. The processing process of the rear torsion beam is: stamping——welding—machining. The part of the rear torsion beam that needs to be machined is the outer surface of the hub bracket on both sides. The two surfaces are left and right symmetrical. ...

AI Technical Summary

Problems solved by technology

At present, the general machining method for the rear torsion beam is to use special equipment or process it in a five-axis machining center. There are problems such as large investment in equipment configuration, long cycle time, and high processing cost. It cannot meet the needs of sample processing and small batch processing in time. production demand
